Authentication problem

[stefanbrunner]

I try to use sipcall for a project with network monitoring.
I would like provide a application thats call a user, when the monitoring server report a problem.

Now I have some authentication problems with pjsua. My provider tells me this:

The client sends us an "Invite" to set up an outgoing call, after a "Trying" then sent a "401 Unauthorized". In the "401 Unauthorized" package from our server contains the hash to encrypt the password. Each outgoing call, the user data is checked before the call is authorized. The client seems, according to the log this to intepret as an error because we have received no answer (see screenshot). Is there a way to set what kind of authentication is used for the connection?

What can i do?

jumping in so old issue.
maybe your provider needs domain name not ip address in realm header.
